computer works

1. HISTORY OF COMPUTER

2. Computer is an electronic device
which accept data as input
through some Input deices,
process that data according to the
stored program and give us the
result as output through some
output devices.

3. Compute mean compute which is “to calculate". there fore the
computer is a machine process or more faster tan a human being
So there it need a man for the works.
the calculation process is start from the 600 BC and name is abacus
Which is use for the calculation ..> The abacus also name
“sorobran”.and it was introduce by cranmer.

4. In earlier 17th century the famous logarithm idea was developed john Napier
the Scottish mathematician, he created the table calculation logrithem

5. In 1642 a scientest of france, name Blaise Pascal
was fist devloped the mechanical calculator or
calculating machine. And its name is pascalene .it
was first calculator in the world.

6. Gotfried von
1671 German mathematician Gottfried developed first calculator for
the multiplication as well as for the other arithmetic calculation. it is
similar to the Pascal calculating machine it use through the gear
system.

7. Punch board system
A French engineer Josef Marie invented a punch board system
for power looms. It was use to design for the clothing specific
weaving patern for the cloths automaticalley later this idea was
used for calculating process.

8. Calculating device Charles Xavier
Arthometer Charles Xavier
This mashine use for the arthematic calculation such as
multiplication ,division adition and subtractioin .

9. Calculating machine by Charles babbge
Mathmatic professor in cambriage university
develop a special type of calculator , it was callled
“differnce machine “which was powered by steam
for mathematical calculation.babbege also called
the father of computer.
Charles Babbage Charles difference machine

10. Charles Babbage analytical engine
It wqs the first programmable computer which work throug
the prorame.it was avrege speed to perform the 60 adition in
Per min.

11. Lady Ada Augusta
It was the student of Charles Babbage work with charles in designing the
“analytical engine “ she was the first programable women which put the
programe
In the analitical engine

12. 1) Punch card by herman hollerth(1860 to 1929). He was introduce the
punch board system and introduce the punch card as input system. he
developed the first electro mechanical punch card
2) Atnaff berry computer. He was invented the electrialmachine to
solve the mathematical problem. It was called atnaff berry computer or
ABC.this working machine was complete in alg1942.
3) Boolean algebra . He was introduced the logic circuit inside the
computer .
4) Mark_1 or ASCC. It stand for ( automatic sequence controlled
calculator ) it was work under the controlled of the punched board .the
instruction give through the punched board. this machine is 50 feet
long 8 feet high 30 feet width. It was basically an electro magnetic
device. In which the electronic and mechanical component were used.
5) ENAIC (1943 to 1946). It stand for electronic numerical integral and
calcutor . It was the first electronic computer. it was developed at
moore school of engineering university in 1943. it contain 18000
vacuum tube and occupied more than 1500 square feet with of weight
of 30 tons.
6) UNIVAC (1951). I stand for the ( universal automatic computer)it wsa
the first digital computer. The program and data were feed through the
magnetic tape.

13. 6) IBM (1952). IBM corporation introduce the new system
which is 701 commercial computer . In 1953 produce 650 and
1000 no's of computer.
